.ToaZl whom it may concern;

Be it known that I, v CARL F. Lunnnenne, a citizen of the United ,States, resid ng ,at 36 Willow, street, city of Hartforid, in the county of Hartford and State of Connecti cut, have invented certain new and.v useful Improvements in Air Purify ng and Cooling Devices, of which the following is a v 1 and through the outlet 13,. wh1le the One object of the invention is to cool the 1 specification.

atmosphere in a room.

A-furthe'r object of the invention is to purify, the air furnishing humid, cool and mild atmosphere free of all dust, etc.

A further object is to provide a currentof purified cool air ,without theuse of any force other than that of'the water entering the device being up er pressure.

Figure 1 is a lateral view partially in Referring to der 1-- is preferably rotatably mounted in an upright position in a standard 2. A supply of water is furnished preferably at the top of said cylinder by means of a pipe 3- preferably having a sprinkler -4 from which water under-pressure is directed downward in said cylinder. Adja- I cent to said sprinkler -4 as through openings -5 at each side thereof and through apertures 66 in the side of said cylinder air is allowed to enter and come in contact with said water under pressure.

. pressure of the water causes a suction in the cylinder which draws in the air through the said openings. The sprinkler might furnish the water in the form of a fine spray, but

preferably it is furnished in jets and mixed with the air by the following means.

A fan 7- with diagonal-blades is Preferably mounted on a sultable bearing 8- secured in a frame 10, Fig. -4, said cylinder in any suitable manner. Asthe jets, of water under pressure strike the fan operating the same the water forms a spray having a whirling action which is thus mixed with the air. vAfter the air is thus cooled and purified. it is separatedfrom the the drawings as the trated embodiment of the invention, a cylin- The said has an opening, as at 11 Fig. 2-, and a sleeve 12- around saidcylinder waterby the following means The'cylinder 3 providing an air space betweenv the sleeve water runs down to the bottom, of the cylinder which is preferably funnel shaped and has a water outlet as at -14-. As the water still has a whirling action caused by the 'fan in order to prevent air escaping through, the water outlet and in order to have the ,outlet take off the water as fast as possible, I provide astop l5 in the side of the funnel of the cylinder to prevent the whirling action of the water and thus keep the outlet filled with water continually. This is especially necessary because the pressure of the water fromthe sprinkler puts the air somewhat under pressure and inorder that the air may all escape through the air outlet, it is necessary that the funnel contain water.

. I prefer to purified and cooled air, but the device may supply a single room with,

be large enough to. supply other rooms if necessary, and the air from the air outlet may be directed and supplied to any room desired.

The operation of the device is simple and rotated thereby to mix said air and water.

in the form of a spray having a whirling action and means for separatmg the air from said Water. held in place on a spindle 9- which is 2. In an air purifying and cooling device,

'a cylinder having an air inlet at the top thereof,.a sprinkler supplying water under pressure to be mixed with said air within said cylinder, means ..for separating the air from said water, said means consisting of a sleeve forming an air chamber between itself and said cylinder, said sleeve-having an air outlet at one'side thereof outof alineat. 7 1mm inent of an opening onthe side of said cylinder whereby air may escape through said opening around sa-idcylinder to the air outsupplying water under pressure adjacent.

thereto, means for mixing said air and Water in a whirling action, means of separating said air and Water, and an outlet for .said water having arranged adjacent thereto means for checking the whirling action of said water'whereby said Water cannot rise and circulate into the air outlet thereabove substantially as described.

4:. In an air purifying and cooling device a cylinder having an air inlet, a sprinkler supplying Water under pressure adjacent thereto, means for separating said air and water consisting of an opening on the side of said cylinder and a sleeve providingan air chamber encircling said cylinder and having an air outlet therein on the opposite side of said cylinder from said opening therein.

5. In an air purifying and cooling device a cylinder having a plurality of air inlets at the to thereof, a sprinkler supplying water un er pressure adj acentto said inlets; said water from said-sprinkler being in the form of jets traveling-substantially parallel to each other and parallel *to the sides of said cylinder; said jets of water operating a fan, without other motive power, adapted init-s revolutions to crush succeeding jets of water, thereby mixing said water and said air, and, means for separating said air and said water, substantially as described.

.6. In an air purifying and cooling device a cylinder having a plurality of air inlets at the top thereof; a sprinkler supplying Water under pressure-adjacent to said inlets;

said water from said sprinkler being in the form of jets traveling substantially parallel to each other and parallel to the sides of said cylinder; said jets of water operating a fan,-without other .motive power, adapted in its revolutions to crush succeeding jets of water, thereby mixing said water and said air, and means for separating said air and said Water; said means consisting of a sleeve providing an air chamber between itself and said cylinder; an air outlet in said sleeve out of alinement with an-air outlet in said cylinder, substantially as described.

In testimony whereof I afix my signature in presence of two witnesses.
